Question

The cost of 1 kg of wheat is Rs. 58. What is the cost of \[4\dfrac{1}{8}\] kgs wheat?

Answer 1

Hint: Here, we will use the given condition as our conversion factor and then compute the cost of \[4\dfrac{1}{8}\] kgs by multiplying it by Rs. \[58\] using the given condition.

Complete step by step answer:

We are given that the cost of 1 kg is Rs 58,

Now we have to compute the cost of \[4\dfrac{1}{8}\] kgs by multiplying it by Rs. \[58\] using the given condition, we get

\[
   \Rightarrow 4\dfrac{1}{8} \times 58 \\
   \Rightarrow \dfrac{{33}}{8} \times 58 \\
   \Rightarrow {\text{Rs. }}239.25 \\
 \]

Thus, we have that the required cost is Rs. \[239.25\].

Note: In solving these types of questions, students should know the basics about cost and kilograms. We have to use the given condition as our conversion factor from kg to rupees. Some students divide the value \[4\dfrac{1}{8}\] by \[58\] instead of multiplying them and they may write the fraction \[\dfrac{4}{8}\] instead of \[\dfrac{{33}}{8}\], which are wrong. This question is simple, but take care of calculations. The cost is a price at which the item is sold.
